Petroleum Jelly

Hello Everyone,



I saw from one of the forums that petroleum jelly is used to lubricate the o-rings of water-resistant flashlights.



My question is this: won't petroleum-based products make the rubber hard and eventually fail?



Yes the secure caps of these flashlights turn easier when opening and replacing batteries, but as i said, wont the o-rings become hard and fail?



Just hoping for some enlightenment from the flashlight gurus! :)



Thank you.
